Form factor and interface

The Dogfish Technology mSATA 256GB is an internal solid-state drive built to the mSATA form factor with a SATA 6 Gb/s interface. It fits desktops and laptops that provide an mSATA slot and need a 256GB capacity boost.

Thermals noise and power

With no moving parts the drive runs silently and adds minimal heat to the system. It operates from 0°C to 75°C and can be stored between -40°C and 85°C. DevSleep support lets the drive enter an ultra-low power state when the host system allows it.

Firmware features

Built-in ECC, wear-levelling and bad-block management protect data integrity over the rated 10,000,000-hour MTBF. The controller also supports SMART monitoring, TRIM and NCQ so the operating system can maintain performance and report health status.

Questions about this item

How do I install this mSATA SSD in my laptop, and what alignment step is often missed?

Insert the drive at an angle into the mSATA slot, press it down flat, and secure it with the retention screw; the step often missed is ensuring the screw is fully tightened so the connector stays seated.

What maintenance or replacement will this 256GB drive need over its life?

No mechanical maintenance is required; firmware updates via the manufacturer tool can improve stability, and the drive should be replaced once the 10000000‑hour MTBF rating is approached or if SMART attributes report worn‑out NAND blocks.

What performance limit appears first during sustained heavy writes on this SATA III drive?

The sequential write speed caps at 300MBps, so extended large‑file transfers will hit that ceiling before the controller or thermal limits (0°C to 75°C operating range) become a factor.
